Just watching that person fly out and crash into the lamp post made Aiden himself feel somewhat pained.
But the other party's plight wasn't worthy of sympathy, the cane was still firmly grasped in the other's hand, Aiden glanced at the end of the other's cane and, sure enough, he saw a segment of a silver blade.
A cane with a concealed blade is nothing but a hollowed-out cane modified with a spring knife inside; the trigger is placed in the handle. It's a common method of self-defense among gangsters and local snakes, next to firearms.
The flash of silver light at the end of the cane had alerted all three present that the cane had a blade attached.
Truth be told, even without Rebecca and Veronica's intervention, Aiden was capable of handling such a surprise attack. Even though he wasn't as skilled as the former Judge he replaced, the level he inherited still qualified him as an excellent swordsman.
